Brain Activity During Sexual Behavior in Patients With Primary Premature Ejaculation a Clinical Trial

This study investigates how the brain functions differently in men who have primary premature ejaculation (PE) compared to men who do not, using near-infrared spectroscopy brain imaging during simulated sexual activity. The research aims to identify whether there are measurable brain activity differences that might explain why some men experience PE. Eligible participants are men aged 18–45 who are in a stable heterosexual relationship with at least two sexual encounters per week — either with a confirmed PE diagnosis or without PE for the control group. Participation involves brain scanning sessions at rest and during simulated sexual tasks, with no medication or invasive procedures involved. This summary was generated by AI to help patients understand the study in plain language.
